Abstract
Tray towers are essentially vertical cylinders in which the liquid and gas are contacted in staged operation on plates, and are useful for distillation and absorption processes. In the present paper the design of a sieve tray tower was carried out for the physical absorption of ammonia using water as the solvent. The calculated values for the tower diameter, gas-pressure drop per tray, entrainment mass flowrate and entrainment-corrected Murphree tray efficiency were 0.962 m; 0.683 kPa/tray; 0.102 kg/s and 0.796 respectively. The calculated values for both the gas-pressure drop per tray and the entrainment mass flowrate are lower than the limits established by the process; therefore, the designed sieve tray tower can be successfully employed for the required mass transfer service.
